In northern India’s Uttarakhand, just outside the Nanda Devi Biosphere Reserve, is Shakti 360˚ Leti, a four-cabin camp named for its panoramic views of the Himalayas. From New Delhi, it’s nearly 12 hours by train, car, and foot to the lodge, which sits 8,000 feet above sea level. The glass-and-stone lodge has a well-curated library and solar-powered electricity. What it doesn’t have: television, Internet, or cell phone coverage.
